Elevated plasma levels of branched-chain amino acids (BCAAs) are associated with an increased risk of insulin resistance and type 2 diabetes, potentially through the persistent activation of mTORC1 and subsequent serine phosphorylation of IRS-1.
If you have insulin resistance or type 2 diabetes, your blood BCAAs might be high, which is linked to worsening insulin sensitivity. While BCAAs are good for muscle building in healthy individuals, chronically high levels in your blood might be a sign of metabolic dysfunction rather than just a supplement effect. Focus on overall metabolic health and protein quality rather than just high-dose BCAA supplementation if you are at risk for diabetes.
an increased BCAA plasma level is associated with a high risk of metabolic disorder and future insulin resistance, or type 2 diabetes mellitus (T2DM). The activation of mammalian target of rapamycin complex 1 (mTORC1) by BCAAs has been suggested to cause insulin resistance.

- BCAA supplementation or high BCAA diets can improve metabolic parameters such as body composition, glucose tolerance, and insulin sensitivity in specific contexts, such as in high-fat diet-fed mice or by stimulating protein synthesis.Moderate
- Impaired BCAA metabolism, specifically reduced activity of enzymes like BCATm and BCKDC, leads to the accumulation of BCAAs and their toxic intermediates, contributing to insulin resistance and mitochondrial dysfunction.Moderate

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
